An experiment was conducted to find out the efficacy of garlic tablets in controlling seed-borne fungal pathogens of cucumber. Suspention of garlic tablet was prepared in water at the concentrations of 1:3, 1:4, 1:5 and 1:6. Seeds of cucumber were treated with the suspentions for 15 minutes. Seeds under control were treated with plain water. Seven fungal pathogens, namely Aspergillus flavus, Aspergillus niger, Fusarium oxysporum, Fusarium moniliforme, Penicillium spp., Doratomycetes sp. and Rhizopus stolonifer were found to be associated with the cucumber seeds. Their prevalence ranged from 1.0-8.0, 1.0-4.0, 1.0-15.0, 1.0-8.0, 0.0-9.0, 1.0-17.0 and 0.0-12.0% respectively under different treatments including control. All concentrations of the material caused significant decrease in the prevalence of seed-bornefungi, occurrence of abnormal seedlings and rotten seeds as compared to control. On the other hand, germination increased over control due to seed treatment with garlic tablet. The higher increase in germination and reduction in occurrence of seed-borne fungi, rotten seed and abnormal seedling were corroborated with higher doses of garlic tablet.

Effect of mehogoni, mehedi and allamanda extracts were tested to control seed borne fungi of okra seeds collected from 6 companies of notunbazar in Mymensingh district. Prevalence of seed borne fungi was studied by blotter method in the Seed Pathology Center (SPC) and MS Laboratory, Department of Plant Pathology, Bangladesh Agricultural University (BAU), Mymensingh. The highest germination percentage was recorded from ACI seeds (88%), while lowest (70%) in BADC seeds. Six predominant fungal genera were identified. These species were Fusarium oxysporum (5.08%), Aspergillus flavus (4.50%), Aspergillus niger (6.50%), Colletotrichum dematium (4.67%), Rhizopus stolonifer (3.33%) and Penicillium spp. (3.00%). Germination percentage and fungal association varied from company to company. The germination was ranged from 70-95% and infections were recorded 0.80-6.1% in all the treated seeds. Mehogoni extracts at the rate of 1:1 showed best performance in increasing seed germination (96.00%) next to allamanda (70%). Vigour index of okra seeds were increased 19.14% over untreated seeds by the treatment of mehogoni seed extracts at the rate of 1:1. Mehogoniseed extract at the rate of 1:1 seemed to be adoptable at the farmer?s level as an organic management practice.Asian J. Med. Biol. Res. December 2015, 1(3): 628-640

Five varieties of diseased onion samples, four local (Taherpuri, Faridpuri, Kalashnagari, and Zitka) and one Indian (Pusa Red) were collected from different markets of Mymensingh, to isolate and identify the associated fungi. Five different fungal species belonging to three genera were repeatedly isolated. Healthy looking and diseased onions were kept at room temperature. The population of associated fungi increased proportionately with the duration of storage period. The isolated fungi were Aspergillus niger, Aspergillus flavus, Penicillium spp., Fusarium oxysporum and Fusarium moniliforme. Healthy onion bulbs were inoculated (with injury and without injury) with these fungi. Individual fungi produced distinguishable symptom of disease in incubation chamber at 22-23°C temperature. After 30 days of inoculation, bulbs showed comparatively low amount of disease development than those at 60 and 90 days. Maximum disease development was found in the variety Pusa Red (with injury) and it was minimum in Zitka variety (without injury).

Wheat and chickpea are considered the most important sources of food and energy and stored for longer period of time in the rural areas in the farmers sheds as seed for the next crop and as market commodity to sale. Both of these crops are liable to many mycoflora which not only deteriorate their quality but also leads toward the crop failure during the coming season. A number of seed borne pathogens viz., Aspergills niger, Aspergillus flavus, Aspergillus sulphureus, Aspergillus nidulense, Rhizopus stolonifer, Penicillium spp. and Drechslera spp, were isolated from wheat seed samples while Aspergillus niger, Aspergillus flavus, Bipolaris spp., Penicillium spp. and Rhizopus stolonifer were isolated from seed samples of chickpea. Various broad spectrum fungicides were evaluated against the isolated mycoflora which showed significant result. Score, Topsin-M and ridomil gold to be the most significant fungicides at all doses against the isolated mycoflora.

The efficacy of seed treatment and foliar spray with fungicides in controlling black point incidence of wheat seeds was evaluated in the field. Two seed treating fungicides, namely Vitavax-200 and Homai-80WP were used @ 0.25% of dry seed weight and foliar spray with Tilt-250EC (0.05%) was applied in six different schedules. Untreated and unsprayed controls were also maintained. Seed treatment with either Vitavax-200 or Homai-80WP significantly increased plant population and grain yield, but none of them was found effective in reducing black point incidence. On the other hand, foliar sprays with Tilt-250EC under all the spray schedules except spraying at 70 and 90 DAS significantly minimized the disease severity over unsprayed control. Among the different spray schedules, spraying at 30, 40, 50, 60, 70, 80, and 90 DAS appeared to be most effective, which was similar to spraying at 30, 45, 60, 75, and 90 DAS in reducing black point incidence and increasing grain yield. Economic analysis on yield advantage showed that the highest additional gross margin of Tk. 6120/ha with BCR 2.57 was obtained from five sprays applied at 30, 45, 60, 75, and 90 DAS.
